MACHINE FOR POLISHING THE HEADS OF TRUNK-NAILS.

Specification of'Letters Patent No. 18,428, dated October 13, 185'?.

To all whom t may concern:

Be it known that we, CORNELIUS VALs-H and ZAoHAn-IAH VALSH, of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Machine for Polishing the Heads of Trunk- Nails Which are Covered or Plated with Sheet-Brass or other Met-al for Ornamental Purposes; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a vertical central section of our improvement taken in the line (90), Fig. 2. Fig. Q is a front view of ditto, the feeding spout being detached. Fig. 3 is a detached side view of the mechanism which rotates the cylinder on which the nails are carried to the ,polishen Similar letters of reference indicate corresponding parts in the .several gures.

This invention consists in .the peculiar means employed for feeding and presenting the heads of the nails to .the polisher, and also in the peculiar yarrangement of the polisher and its connection with .the feeding device; whereby the above parts are made to eect the desired purpose, in a perfect and yexpeditious manner.

To enable those skilled in theart .to fully understand and construct our invention, we will proceed to .describe it.

A, represents a platform or base, on which an upright B, is placed; and C, `is an incline bar, the `lower end of which is attached to the lbar A, and the upper end `to .the upper part of the 4upright B, as shown clearly in Fig. l. On the bar C, .are placed and firmly secured two parallel lmetal bars D, D. On each bar D, a way or guide (a) is placed; the two ways or guides being at corresponding point-s on the bar D; and between the two ways or guides a frame E is placed; said frame being allowed to work freely between the ways or guides. :In the frame E there is placed an arbor (b), having a pulley (c) on it; this arbor passes through the lower cross piece of the frame E, and is screwed into the upper end of a small cylinder (CZ) the arbor having a shoulder on its lower part to serve as a bearing. The upper end of the arbor (b) has a center point (e), fitted into it; said point being at the end of a screw f, which passes through a nut (g) on the upper cross piece of the frame E.

F, is a spring formed of a strip of steel, cut so as to have parallel sides. The .ends of these sides are interposed between .the upper end of the screw and a cam G, which is placed on a shaft H.

The cylinder is hollow -or tubular, and a rod (g") is fitted therein; the upper end of this rod is screwed vinto .the lower end of the arbor (b),l 4and a recess is made in the cylinder by which said rod is rendered accessible anda Vlever allowed to be tted therein, so that the rod may be turned and screwed higher .up .or lower down within the cylinder, .as -desired.

In the lower end of the cylinder (di), leather,

buff, or any suitable polishing material is placed, see Fig. l.

On one end .of vthe shaft Ha driving .pul ley I is placed loosely. This pulley is connected with the shaft H by means .of ya :usual clutch J, which Vis operated by a lever K connected with .a treadle La; see Fig. .2.

At the lower .ends of the bars VD D .ashaft M is placed. This shaft M is 1parallel with the shaft H, and .has .a cylinder or wheel N placed on it between the .bars D, D; and a ratchet wheel O is secured permanently .to it, at one end. On the shaft M and ad] oining the wheel N, a :lever P is placed loosely. The outer .end of this lever is connected by an arm G, with va crank Ipulley R at .one end of the shaft The vlever P has va pawl (j.) attached to it, which pawl is wkept against the face of the ratchet by .a spring '(72) see more particularly Fig. 3. The lever .at the opposite side has .a .projection (Z) formed on it. A pawl which Vis attached to one of `the -bars D, .catches linto the ratchet 0; said ,pawl having a spring (m) leaning against its upper surface. A pawl (mx) also catches into the vratchet O, at its under side. The .cylinder or wheel N has a series of radial tubes (n), fitted in -its periphery; and ithe tubes extend Lenti-rely around the wheel at equal distances apart, as shown clearly in Fig. l.

S, is a tube or spout which is sustained in an inclined position by a curved bar or rod (o). This tube or spout has a radial position relatively with the cylinder or wheel N, as shown clearly in Fig. l. The bottom or lower side of the tube S, has a slot or groove (p) made longitudinally through it;

and a stop T which is formed by having a forked termination at one end of a spring plate (g), is fitted over the lower end of the tube or spout S. To the end of this stop T the lowerend of a rod (r) is attached; the upper end of said rod being connected to an arm U, which is hinged or connected by a joint (s) to the upper part of the inclined bar C. The arm U has a projection (v) attached, which projection is acted upon by a cam V, adjoining the cam G. The upper end of the frame E is connected by a rod (w) with a spring (ax), attached to the upper part of the inclined bar C.

To the inner side of the pulley I, a larger pulley W is attached; and (35X) is a belt which passes around said pulley, and also around a pulley (0X) on a shaft X, placed in proper bearings at one end of the base A. On the shaft X a pulley ZX is placed, around which a belt (ex) passes; said belt also passing around the pulley (c) on the arbor (o).

The operation is as follows The tube or spout S is filled with nails, the shanks or points being placed first in the tube or spout as shown in red, Fig. l. lWIotion is given to the shaft H in any proper manner, and a continuous rotary movement is given the cylinder (d), by means of the belts (bx) and (6*), which pass around their respective pulleys, as shown. The cylinder N is rotated intermittently, by means of the crank pulley R, rod G, arm or lever P, and the pawl (j), arranged as shown; the pawls (my) (mx) retaining or holding the ratchet during the upper movement of the pawl so as to prevent the casual movement of said ratchet. The nails are fed into the tubes (n) as they pass successively in line with the spout or tube S, and the shanks of the nails are guided into the tubes by the slot or groove (p). The nails are allowed to pass out of the spout or tube by the raising of the stop T, which is done at the moment each tube (n), comes in line with the spout or tube S in consequence of the cam V actuating the arm U; the cylinder or wheel N, dwelling a short time as each tube passes in line with said spout or tube. At the same time that a tube (u) is in line with the tube or spout S, there is a tube (u) in line with the cylinder or wheel N; the cylinder (d) which contains the polishing material (i), is depressed by the cam Gr, which acts directly upon the spring F; the latter being sufliciently stili" to cause the frame E and the cylinder (d) to be depressed, and the polishing material (i) to be pressed suthciently hard upon the heads of the nails as they pass successively underneath it, to cause the heads thereof to be perfectly polished. The spring F, it will be seen, compensates for the wear of the polishing substance or material; and when said substance is worn or reduced so much that the spring F is unable to compensate for it, the substance is forced farther down within the cylinder (d) by turning the rod (g). The frame E is raised by the spring (ax) when the prominent portion of the cam G passes the spring F; and the cams Gr, V, and the connector of the rod G with the crank pulley R, are so placed relatively with each other that the cylinder or wheel N, step T, and the downward movement of tlie cylinder (CZ), take place at the precise time so that said parts may act automatically as described.

It will be understood that the foot of the operator is kept upon the treadle L when the machine is in operation, in order to keep the pulley I in gear with the shaft H. The polished nails fall out of the tubes (n) as they pass around and reach an inverted vertical position.

VVe would remark that the cylinder or wheel N may be so arranged as to be placed in a horizontal position; but we prefer the vertical wheel, as the nails are thereby allowed to discharge themselves by their own gravity.

Having thus described our invention, what we claim as new, and desire to secure by Letters-Patent, is:

l. The rotating and vertically reciprocating cylinder (CZ), provided with the polishing substance in combination with the intermittingly rotating Cylinder N, provided with radial tubes (n), to receive and hold the nails; the above parts being arranged to operate as shown, for the purpose set forth.

2. We also claim the arrangement of the stop T, relatively to the spout or tube S, cylinder N, and cams Gr, V, so that it shall be caused to rise at proper intervals and thus feed the nails regularly out of the tube to the cylinder N, substantially as herein described.
